There once a depressed Frog.
His depressions were a result of the colour of his genitals being bright yellow, this made it very difficult for him to find himself a mate.
So the Frog looked for assistance and was told to go to the Fairy Godmother's house on the edge of the Forest. Here he asked her if she could help him but she replied 'Sorry, dear, I can't do anything to help there. You'll have to go see the Wizard of Oz'. So the Frog left full of optimism to the Wizard's house.
The Fairy Godmother's next customer was a Bear. But unlike most bears who had brown paws he had bright purple ones which made it difficult to find a mate.
Once again the Fairy Godmother said that she couldn't help and once again she said that the Wizard of Oz would help.
The bear asked 'Where the hell does the Wizard of Oz live?' and the Fairy Godmother replied, 'just follow the Yellow Dick Toad'.
